Troubleshooting

There is not sufficient range

The LT-700 is a portable transmitter that uses the microphone cable as an antenna and the range will vary depending on the location of the receivers compared to the transmitter. You can only expect about 100 feet of average effective working range.

It’s confusing for users to have 32 channels when switching between channels

Use the PROGRAM function to lock out unwanted channels. This way, users will only need to scroll among a few channels.

I cannot change the channel

It is probably locked (check for the padlock icon). To unlock, press and hold the UP or DOWN button for 5 seconds.

My batteries are not charging

Make sure you are using NiMH batteries and that the BATTERY SELECT switch (inside the battery compartment) is set to the NiMH position. Make sure the batteries are installed correctly. Make sure you are using the right kind of wall transformer (Listen part number LA-208) or charging case. Make sure the charging case is connected to power and the unit is securely pushed into its slot in the case.

NOTE: Listen uses 2300 mAh (milli-Amp-hour) constant current NiMH (Nickel Metal Hydride) batteries. These may be purchased from your Listen dealer (ask for part number LA-362).
